Abstract

A novel system and method of treating the output of moving cameras, in particular ones that enable the application of conventional “static camera” algorithms, e.g., to enable the continuous vigilance of computer surveillance technology to be applied to moving cameras that cover a wide area. According to the invention, a single camera is deployed to cover an area that might require many static cameras and a corresponding number of processing units. A novel system for processing the main video sufficiently enables long-term change detection, particularly the observation that a static object has been moved or has appeared, for instance detecting the parking and departure of vehicles in a parking lot, the arrival of trains in stations, delivery of goods, arrival and dispersal of people, or any other application.

Claims

1. A system for analyzing images acquired from a single non-static imaging device having a field of view that changes over time, the system comprising:

a means for receiving said images and processing said images to create a first mosaic image from one or more received image frames, said means further generating successive mosaic images registered to the first mosaic image.

2. The system as claimed in claim 1, further comprising a means for analyzing each of said successive mosaic images for detecting a change in a desired feature of the observed area.

3. A method for analyzing images acquired from a single non-static imaging device having a field of view that changes over time, the system comprising:

processing received said images to create a first mosaic image from one or more received image frames, and,

generating successive mosaic images registered to the first mosaic image.

4. The method as claimed in claim 3, further comprising the step of analyzing each of said successive mosaic images for detecting a change in a desired feature of the observed area.
